Polymer Blends and Alloys: Innovations for En-
hanced Performance
process is basically through mechanical blend-
ing which often requires melting of the polymers
and blending them. The blend can also possess
a combination of properties for instance higher
notch toughness, better chemical resistance or
improved process ability.
For example, incorporating a high-density poly-
ethylene (HDPE) with a low-density polyethyl-
ene (LDPE) can produce a material that enjoys
the former’s high impact strength and the lat-
ter’s flexibility. This kind of blend can be em-
ployed in packaging material where the prop-
erty of strength as well as flexibility is required.
Exploring Polymer Alloys
Polymer alloys are one of the categories of pol-
ymer blends which produce a material that has
